What do all diff. connective tissues have in common?
cells are surrounded by a matrix
What's in the matrix?
hard an dense, like bones or could be soft (jelly-like or lliquid)
____ is a Connective Tissue.

Bone itself is____.
Compact Bone
In____'s matrix it's components are: bone cells,which secrete a matrix to surround the cells

Cells surrounded by matrix are___.
extracellular
What are the two different parts of the extrcellular matrix?
Inorganic and Organic
____are 2/3, Rigid Hard stuff and give us the ability to sit up right.
Inorganic
Inorganic are composed of what two salts?
Calcium Phosphate(75%) and Calcium Carbonate
___from inorganic materials are very tough.
Calcium Phosphate
____ and ___ give us the major framework of the bone itself.
Calcium Phosphate(75%) and Calcium Carbonate
___ in matrix+Calcium Carbonate+Calcium Phosphate gives it
Collagen Fibers
What is minerals found in bone, which are also calcium compounds found inside bones?

Bone Cells
___ reabsorb and break bones down.
Cells
Two Cells in bone are____ and ______.
Osteoblast and Osteoclast

Osteoblast
____produces more of the extracellular matrix, produces collagen that lays down__ and ___
for Collagen to create more new matrix.
Osteoblasts,Calcium Phosphate and Calcium Carbonate
___is a bone cell.
Osteocyte
____surrounds itself with matix, becomes incapsulated and becomes a osteocyte.
Osteoblast
What do you get if you over produce bone?
Gigantism and Actromegaly
____is where you have a over growth disease.
Gigantism
What is the main reason to lay down Calcium C and Calcium P?
Bones are now storing Calcium
Why is it good to store calcium in the bones?
strength,we can use Ca if we need to
Why is Ca important?
nerve impulses at the synaptic knob
___ moves in once the action potential hits the synaptic knob and release a Neurotransmitter.
Calcium
____ important in nerve production or muscle contractions.
Calcium
What two hormones that Control Ca?
